Document Description
The City initiated planning for the ongoing Phase II WWTP expansion project in 2016 to expand the treatment capacity from 5 million gallons per day (MGD) average dry weather flow (ADWF) to 7.5 MGD ADWF. The City prepared an Initial Study to evaluate potential environmental impacts from construction and operation of the Project and adopted a Mitigated Negative Declaration (MND) on August 9, 2016. As originally proposed, the Project involved construction of a biosolids dryer building and storage silo as a means of producing Class A biosolids, thus facilitating additional uses or disposal methods for the biosolids. The City has since decided to use different technology and place the biosolids drying facilities at a different location. The project modifications consist of the following main components.
1. Installation of a biosolids drying and pyrolysis system (BDPS) outside of the existing footprint of the WWTP.
2. Realignment of a paved connector path to the Marsh Creek trail.
3. Installation of new WWTP perimeter fencing around the BDPS.
4. Tree removal.
All project components would be constructed on 4 acres of City-owned property immediately adjacent to the east boundary of the current WWTP
